Biggest thing for me was that Jolly is listed as a DE. He could still play NT, I guess, since he is 310. From what I've seen so far, both Raji and Pickett will be starters, meaning that you can hardly see that as depth at a position.
Then we have the other two guys. One is pretty undersized and underweigth for the position (see my last post), although it still is a possibility. The other one is a NT/DE and that's with a reason. He doesn't have the weight by far. He's 6'3 and 295 LBS. That's less than Cullen Jenkins. Maybe he has the frame to put on some weigth, but I still remember the way that went with Foster's favorite.
I don't think that we'll need 6 players to have decent depth, 3 is enough, maybe stash one on the practice squad. It just doesn't look that impressive to me right now.
